On the odd occasion that a person is referred to your campaign by two or more different people, our system will allocate the referral to the referrer whose link was used first.
For example: Jessica gets referred by Alex and Stacey. Jessica uses Stacey's link to sign up to your campaign. Referral Factory will assign the referral to Stacey.
Our system only allows a person to register for a campaign with their email address once so if Jessica registers with both Alex, and Stacey's referral link, she will only be in the campaign once.
